Bt878 Video Capture/TV Tuner problems in Fedora Core 3


I have a brand new install of Fedora Core 3 and I am very impressed! its so smooth compared to the earlier releases. Anyway, the first thing I wanted to do was see if my TV tuner was supported and working. From what I've read around, it is supported, but some people have had problems, like me. It just doesn't work. the box said it was a 'prolink pixelview something' but I read somewhere that's not the best way to identify the card. it works OK in Windows but I'm really getting sick of its little problems that no one can fix or even troubleshoot without saying, "format and/or reinstall" &$!#&!&$!@#$!@
I am trying it with tvtime because it was available on the install DVD. Is there one more compatible perhaps?
i would like to post a link to a possible solution but im still new. maybe there is another way.

-----------UNAME------------ all of it

that all looks perfectly normal and correct.... what's actually not happening? have you tried setting the correct frequency table and encoding for your country?

i'd personally recommend xawtv to get started with, and then if you want to use up your cpu for no good reason, try tvtime again

Hi and thanks for the advice.
I read something on the tvtime website that says this shouldn't be like this

-----dmesg-----
bttv0: using: *** UNKNOWN/GENERIC *** [card=0,autodetected]
bttv0: gpio: en=00000000, out=00000000 in=00ffc0ff [init]
bttv: readee error
bttv0: using tuner=-1

i read that the "tuner=-1" means that the tuner isnt detected right.
as well some other place suggest that for this model of card the card=0 should be 32 or 70 or 72 depending on the actual chips on the card.

i will try xawtv now tho and see if I can get it working. if I can figure it out I will reply back so other newbs can find out what there missing.
thanks again.

Question ?????

i dont know. im still kinda stumped. xawtv looks like its getting something. static at least.

I live in canada so i set the TV norm to NTSC and tried the frequency table at the 3 us settings and no go.
the cable is definitly hooked into the card. Its a MS XBox and it worked yesterday when I had windows still installed.

its coaxial not svid or composite and its set right for that. if somebody doesnt mind helpin with this I can PM them a link to a site that might describe my problem.
or even better do a search on google for "pixelview tvtime" and it will be the first link that comes up. then it is item number six on that page.

Go to this website: http://linux.bytesex.org/v4l2/bttv.html and download the bttv package. The included docs contain lists of cards and tuners based on the BT8xx chipset. Check out CARDLIST.bttv and CARDLIST.tuner for your card and onboard tuner. Add this line to /etc/modprobe.conf:

options bttv card=xx tuner=yy

with xx and yy being your card and tuner numbers. This should get your tuner up and running. It did mine.

Hope this helps.

Great! I was able to get my TV/FM Card working! I have not managed to get the FM Card working but that really dosen't bother me since I listen to online radio. Anyway, I do need some help! I got the card working but the image is in Black and White and not color. It is in color when in Windows and works fine.

Here is more information about my card and kernel etc.....

Uname -a

[jordie@Jordie jordie]$ uname -a
Linux Gateway.2wire.net 2.6.9-1.3_FC2 #1 Mon Nov 15 14:46:43 EST 2004 i686 i686 i386 GNU/Linux

I installed the drivers from that site http://linux.bytesex.org/v4l2/bttv.html.

I added this to modprobe.conf

#TV Card
alias char-major-89 i2c-dev
alias char-major-81 bttv
options bttv card=62 tuner=5 radio=1

And downloaded xawtv and kdetv. I am using kdetv, I find the interface easier to use then xawtv. Anyway, can anyone help me with this issue? If I can get it in color I will now be gone with WIndows totally and that is my goal!

After rebooting and messing around with Kdetv for a few minutes I was finally able to get it in color! Linux rocks.

If Linux ever did become a mainstream desktop OS alot of this work I have done to get my tv card working would need to be changed to make it easy for novice users.

I swtched from FC3 to Ubunto and my card worked perfectly out of the box. I just had to apt-get install xawtv.
It worked great, but then i seen this post again and it reminded me to try out tvtime. It works great too.
